.WEATHER-STRIP FOR DOORS OR WINDOWS.

SPECIFICATION forming part of Letters IPatent No. 660,839, dated October 30, 1900.

Application filed March 10, 1900- fierial No. 8,191. (No model.)

To all whom it may concern:

Be it known that I, JESSE E. BUNDY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvementin Weather-Strips for Doors or Windows; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device for hermetically closing the bottoms of doors, windows, and the like against the entrance of wind, rain, and snow.

It consists of a movable tilting strip forming a continuation of the threshold or seat over which the door normally closes and so guided that when the door is closed the inner edge of the strip will be tilted upwardly against the lower edge of the door and form a joint with a molding of suitable character which fits across the lower part of the'door for that purpose. When the door is opened, this piece falls by gravitation to its normal position,where it forms a portion of the threshold.

My invention also comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a transverse section in the line of the groove showing the door open. Fig. 2 is a similar view, the door beihg closed. Fig.

3 shows my improvement applied to double doors.

I have here illustrated my invention as applied to a hinged swinging door. It will be manifest that it may be equally well fixed to a hinged swinging window-sash or to any other equivalent swinging device where it is desirable to make a joint at the bottom when closed.

As here shown, A is the door, 2 is the doorcasing, and 3 is the 'jamb against which the door closes.

4 is 'the threshold, which is convex-or otherwise suitably shaped upon thesurface and extends to a line just inside of the jamb against which the door closes. From this line it is beveled outwardly, as shown at 5, and thence it extends down to the level of the sill or surface upon which the threshold bottom adapted to rest upon the exterior sill or surface and the top convexity declining outwardly, so that when in place it forms, with the threshold,a complete are or whatever shape the top of the threshold may be. The jambs or sides against which the door closes are cut away at the bottom in an arched form, as shown at 7, so that this strip, resting upon its outer edge, may have its inner edge tilted upwardly above the level of the top of the threshold. This tilting is elfected as follows:

8 is a strip or bar of metalfixed to and projecting from the bottom of the door, and a shallow groove or channel 9 may be formed in the threshold in line with the path of travel the outer face of the bottom of the door when the latter is closed. This covers the crack or opening at the bottom of the door, and in order to insure a close joint at the top of the strip I fix an ogee 11 or other molding horizontally along the outer face of the door at such a point that the loose threshold-section moving up will just contact with it when the door is closed and will form a perfectly-tight joint. If desired, any soft material, as felt or rubber 20, may be fixed beneath the molding, so as to insure a tight joint; The bevelof the inside face of the strip is such that when it is pushed up, as described, and the outer edge rests upon the outer portion of the thresheld this beveled or inclined inner face will stand approximately vertical along the face of the door. The jambs against which the door closes are cut away, as shown at '7, so that while covering the ends of the movable strip they also allow it to rise, and when it is raised by the contact of the door it fits closely against these cut-away portions and forms a joint at that point.

I have hitherto described the device as applied to single doors; but it will be manifest that the device can be similarly applied to double doors closing in the center, as shown in Fig. 3. In this construction the doorAis represented as the one ordinarily used, and A is the one which usually remains closed. The tilting strip 6 extends entirely across the door-opening and is actuated by the projection 8 when the door A is closed, as previously described; but as the door A is closed and overlaps the edge of the strip 6 it is necessary to bevel the lower outer edge of the door A, as shown at 12, to permit the strip to rise freely. For the same reason the edge of the door A should be beveled diagonally, as'shown at 10, because as it turns about its hinges in closing the part nearest the hinge side will be projected over the strip 6 before the lug 8 begins to move it. This cut-away portion is common to the single door and allows the strip to rise as soon as the door has been sufficiently closed to cause the lug 8 to contact with the tilting strip.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a door and in combination with the casing cut away at its lower sides, a threshold having the exterior face beveled or inclined outwardly on the closing-line of the bottom of the door, and having a groove or channel made transversely across its upper surface, a loose strip correspondingin thickness with the threshold and having the bottom adapted to normally and squarely rest upon the threshold-support, the inner edge beveled to coincide with that of the threshold, and the upper surface forminga smooth continuation of the threshold, and a contact piece carried by the doorand movable in said groove or channel, and adapted to strike the edge of the loose piece and cause it to tilt upward along the lower outer face of the door when the latter is closed.

2. In combination with a door and easing thereof, said casing cut away at the lower sides, a threshold having the outer portion cut away on the closing-line of the door and beveled outwardly, a loose strip substantially corresponding with the thickness of the threshold and fitting the bottom and inner bevel, and in its uppersurface normally forming a continuation of the threshold, a contact-piece carried by the door adapted to strike the loose strip and cause it to tilt upwardly against the face of the door when the latter is closed, the horizontal molding or strip fixed to the door and forming an overlap and joint with the upper edge of said strip, and a strip of yielding material secured beneath the molding and against which the upper inner edge of the loose strip strikes to make a tight joint.

3. Doors hinged and closing together on a central line, a threshold having its outer face cut away and beveled outwardly, an independent strip similarly beveled and fitting against the outer edge of the threshold and normally forming a continuation thereof, a contact-piece upon one of the doors adapted to engage said strips and tilt it upward to form a joint along the outer lower faces of both doors, said doors having their lower outer edges beveled to allow the strip to rise without impediment.

In witness whereof I have hereunto set my hand.
